Ye Htet A.

I'm a full-stack engineer with 7 years of TypeScript and Node.js. I build search, data-heavy backends and real-time features, and I fix them when they get slow. I currently work on search infrastructure at PropertyScout, a Bangkok real estate platform with 250,000+ listings: Elasticsearch-based search, PostgreSQL, real-time WebSocket features and distributed services in production. What I can help with: - Elasticsearch / OpenSearch: index and mapping design, search queries and filters, keeping the index in sync with your database - PostgreSQL performance: slow queries, query plans and indexing - Real-time features: WebSockets, live updates and notifications - Next.js and Node.js apps end to end, including Stripe payments and Claude / LLM API integrations - Taking over an existing codebase and making it stable, tested and documented Products I've built on the side: MenuQR, an AI-powered QR menu SaaS for restaurants (Next.js, PostgreSQL, Stripe, Claude API), and SlipShare, a bill-splitting app for iOS, Android and web (Expo / React Native). How I work: clear scope up front, written daily updates, pull requests with tests, and before-and-after numbers for anything performance-related. I'm in Bangkok (UTC+7) and overlap with European afternoons and US East Coast mornings. Send me the problem and I'll tell you how I'd approach it.
